Description
Schweltrommel. Es besteht bei den bekannten Schweltrommeln der Nachteil, daß der große Umfang der Trommel nur verhältnismäßig wenig zur direkten Wärmeübertragung ausgenutzt wird, und es sind, daher verschiedene Wege vorgeschlagen worden, um den Durchsatz in Schweltrommeln zu erhöhen, sie basierten aber meistens darauf, durch Rippen und Leisten die Oberfläche zu vergrößern.Smoldering drum. The known smoldering drums have the disadvantage that the large circumference of the drum only allows relatively little direct heat transfer is exploited, and therefore various ways have been proposed to the Increasing throughput in smoldering drums, but they were mostly based on through Ribs and moldings to enlarge the surface.
Nachfolgend beschriebene Trommel behebt zum großen Teil den vorerwähnten Mangel der Schweltrommel: Auf dem Umfang der Trommel sind Kammerna eingebaut, deren Höhe von der Art der zu verarbeitenden Kohle abhängig ist; diese Kammern können Zwischenräume b zwischen einander haben oder direkt aneinander anschließen, so daß sie einen geschlossenen Ring bilden. Die Kammern sind ferner in der Längsrichtung unterbrochen, derart, daB z. B. die Kammern z m lang sind, dann folgt eine i m lange freie Zone c, und dann kommt wieder eine a m lange Kammer. Je nach der Stärke der zu erwartenden Dampf-oder Gasentwicklung werden die Kammern verschieden lang gehalten. Die Kammern sind deswegen in der Längsrichtung unterbrochen, um empfindliche Schwelprodukte nicht zu lange in nächster Nähe der heißen Ofenwand zu belassen. Die Schwelgase- entweichen in .den kammerfreien Raum und ziehen dann, da sie sich stets den bequemsten Weg suchen, ins Innere des Ofens zur Abzugsleitung.The drum described below largely eliminates the aforementioned Deficiency of the smoldering drum: On the circumference of the drum chambers are built Height of the type depends on the coal to be processed; these Chambers can have spaces b between each other or directly adjoin each other, so that they form a closed ring. The chambers are also in the longitudinal direction interrupted in such a way that z. B. the chambers are z m long, then follows an i m long free zone c, and then there is another a m long chamber. Depending on the strength of the expected evolution of vapor or gas, the chambers are kept for different lengths of time. The chambers are therefore interrupted in the longitudinal direction to avoid sensitive carbonization products not to be left in close proximity to the hot oven wall for too long. The smoldering gas escape in the chamber-free space and then pull, as they are always the most comfortable Look for a way into the interior of the furnace to the exhaust pipe.
Diese neue Einrichtung hat den Vorteil, daß erstens die beheizte Trümmelfläche für direkte Wärmeübertragung bedeutend mehr ausgenutzt wird, zweitens, daß die strahlende Wärme der Ofenwand viel mehr zur Geltung kommt wegen der geringen Entfernung des Schwelgutes von der Ofenwand, da die Strah- lungswärme umgekehrt zum. Quadrat der Entfernung wirksam ist.This new device has the advantage that, firstly, the heated debris surface is used significantly more for direct heat transfer, and secondly, that the radiant heat of the furnace wall is much more effective because of the small distance of the smoldering material from the furnace wall, since the radiant heat is reversed to . Square of distance is effective.
